What was the modified mercalli scale in the sumatra earthquake 2004?

The Modified Mercalli Intensity (MMI) scale for the 2004 Sumatra earthquake, which struck on December 26, was reported to be as high as IX (Violent) in some areas, indicating widespread damage. This scale measures the effects of an earthquake based on human observation and structural damage rather than seismic data. The earthquake, with a magnitude of 9.1, caused significant destruction and loss of life across multiple countries, particularly in Indonesia, Sri Lanka, and Thailand. The intense shaking and subsequent tsunami resulted in catastrophic impacts, further underscoring the severity of the event.
